In this paper, a novel design of an E-plane waveguide filter, called electromagnetically induced transparency (EMIT) filter, is proposed. This EMIT filter is implemented by a rectangular ring (RR) on one side of the substrate and two strip lines resonators (SLRs) on the opposite side, which brings in electrically induced transparency and magnetically induced transparency by the electrical and magnetic...
In this paper, a low-profile dual-polarized antenna integrated with bandpass filter based on dual-mode open-loop resonant is proposed. The antenna design employs the concept of multistacked square patches fed by two probes located in two orthogonal directions. The two bandpass filters used to feed the antenna are on the bottom layer which share the same ground with the antenna. Both the separate and...
This paper attempts to present a novel low-cost testing method for the measurement of band-pass filter testing. The study directs our attention to reduce the cost of test using a simple circuit such as a down-convertor mixer. The band-pass filter is tested by inputting the five critical frequency points. And then the five data which the high frequency had been converted down to 20MHz were collected...
